<P>I don't know if this helps but I have an Canon 750D and also have lines, there are 7 broad lines that can be seen on the sencor directly, see <A href="http://www.cloudynights.com/topic/512886-canon-banding-help/page-3" target="_blank">http://www.cloudynights.com/topic/512886-canon-banding-help/page-3</A>.</P><P>I don't use a memory card on the camera as I have it connected directly to the computer when I am using it in astrophotography so it got nothing to do with a memory card. Many seems to have this problem with 750 and 760D and it seems like an issue with the sensor itself. If I sort the pic in channels it is worse in the blue channel.</P><P><IMG src="https://community.usa.canon.com/t5/image/serverpage/image-id/12703i9226EB1346E23E42/image-size/original?v=1.0&amp;px=-1" border="0" alt="Canon750D.jpg" title="Canon750D.jpg" /></P><P>Cleaning the sensor will not cure this.

<P>Hello!<BR /><BR />I bought a Canon Rebel T6I a few months ago and I just took it outside for a spin. I've noticed in all of my photos outside I have these weird bars. I have no idea why. I figured maybe it could've been the weather since it's been horrendously cold lately, but today I went out to test if it was the bad weather and took a photograph instantly and it's still there. &nbsp;I came here hoping that people who know photography would be able to tell me what this is and what may be causing it? It seems to only happen in they sky of my photos. I've taken indoor photos and they don't seem to be appearent. I have edited these in Lightroom and cropped them in Photoshop so they're more visable. The second image I edited it heavly to show it incase if its not all the visible in the first image. The second image it was snowing when I took it. Sorry for the black mess in it. is it noise banding? I've been feverishly looking online for information but alas I have not been able to find anything that seems close to my issue.&nbsp;</P><P><BR />Sorry if something like this has been asked before. I am truely desperate to find out what's going on. I hope its something that I can prevent from happening and not my camera.&nbsp;<BR /><BR />I shot these with a Rokinon 14 mm lens if that helps. Thank you's any information would be truley grateful.&nbsp;<BR /><BR /><IMG src="https://community.usa.canon.com/t5/image/serverpage/image-id/12478i609215D19855EEB1/image-size/original?v=1.0&amp;px=-1" border="0" alt="banding 1.jpg" title="banding 1.jpg" /><IMG src="https://community.usa.canon.com/t5/image/serverpage/image-id/12480iFC293DF222CF7D1D/image-size/original?v=1.0&amp;px=-1" border="0" alt="banding 1.png" title="banding 1.png" /></P>Fri, 10 Feb 2017 21:52:15 GMThttps://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/200363#M15760ElectricMuppet2017-02-10T21:52:15ZRe: Rebel T6I Sky Banding?https://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/200377#M15761
<P>I don't see banding - or any other issues in the top one.</P><P>&nbsp;</P><P>The lower one seems to have some sensor dust and those wierd reflections/artifacts but no banding.</P><P>&nbsp;</P><P>What JPEG setting are you using?</P>Sat, 11 Feb 2017 00:26:24 GMThttps://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/200377#M15761kvbarkley2017-02-11T00:26:24ZRe: Rebel T6I Sky Banding?https://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/200384#M15763
<P>Thank you for the reply kvbarkley!<BR /><BR />I am shooting in RAW. Those black lines in the photo are infact snow falling and not dust on my sensor.&nbsp;<BR />I highlighted the falling snow in red. It's the blue box im worried about. Those lines are in all my photos in the daylight but not in my photos at night or indoors. &nbsp;I've used a curves layer to hopefully help you's see the lines better. It's hard to see it in raw until its edited.&nbsp;<BR /><BR />I don't know whats causing it. I just went outside and took an image of the snowy street under a street light and everything seems fine in it during night time.<BR /><BR /><IMG src="https://community.usa.canon.com/t5/image/serverpage/image-id/12481i6AC9A0AFA2AC6515/image-size/original?v=1.0&amp;px=-1" border="0" alt="banding2.png" title="banding2.png" /><IMG src="https://community.usa.canon.com/t5/image/serverpage/image-id/12482i75A26F62CD3C15BB/image-size/original?v=1.0&amp;px=-1" border="0" alt="IMG_2256.png" title="IMG_2256.png" /></P>Sat, 11 Feb 2017 00:51:34 GMThttps://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/200384#M15763ElectricMuppet2017-02-11T00:51:34ZRe: Rebel T6I Sky Banding?https://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/200386#M15764
<P>If you are shooting RAW, then turn off all of the noise reduction settings. &nbsp;You should have a high ISO noise reduction. &nbsp;There should be a long exposure noise reduction. &nbsp;Disable the any auto lighting optimizer. &nbsp;All of those settings, and more, can be realized in post processing, so it is not necessary for the camera to implement them.</P>Sat, 11 Feb 2017 01:05:14 GMThttps://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/200386#M15764Waddizzle2017-02-11T01:05:14ZRe: Rebel T6I Sky Banding?https://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/200396#M15766
<P>I see 14 lines (7 pairs) in the first one and with exactly same distance to each other.

<P>Thank you Peter for the reply!<BR /><BR />That's unfortunetly something I did not want to hear. I just bought the camera two months ago, December 16th to be exact.

I bought my T6S in December also, and it has no trace of banding even with heavy cropping.

<P>Peter is correct except&nbsp;this isn't going to be something that can be "mapped out". &nbsp;You need to have Canon evaluate your camera as I think they will get you another one. &nbsp;This shouldn't, won't, cost you anything&nbsp;but time.</P><P>&nbsp;</P><P>But before you send it in, buy a new high quality SD card and re-try. &nbsp;Get a name brand SD card never use off brand or cheap SD cards. &nbsp;They can do exactly what you are seeing.</P>Sat, 11 Feb 2017 14:18:12 GMThttps://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/200412#M15770ebiggs12017-02-11T14:18:12ZRe: Rebel T6I Sky Banding?https://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/200413#M15771

<P>I just got my camera back today from Canon after they shipped it by the worst postal service they could find. on the repair paper they claim to have replaced the cmos assembly unit.... The problem is still there. It feels good to waste $40 in shipping to have a problem not fixed. Is there anyway I could edit around this stupid problem? I don't see why they didn't test the camera before shipping it back to me.<BR /><BR /><BR />Edit: Looks like they have gunk on my sensor as well. Seems to be massive blotches on my photos. How can they mess up this bad. I got it returned to me in<STRONG> worse condition</STRONG> then it was in. Like what the **bleep**. Now if I want to use this peice of crap I have to pay <STRONG>more money</STRONG> to have this stupid sensor cleaned.<BR /><BR /></P><P>&nbsp;</P><P><IMG src="https://community.usa.canon.com/t5/image/serverpage/image-id/12553i2907B361EA85BEBF/image-size/original?v=1.0&amp;px=-1" border="0" alt="IMG_0012.png" title="IMG_0012.png" /></P>Wed, 22 Feb 2017 17:39:14 GMThttps://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/201378#M16010ElectricMuppet2017-02-22T17:39:14ZRe: Rebel T6I Sky Banding?https://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/201384#M16014

<P>Yes I have the nifty fifty.</P><P>&nbsp;</P><P>I'll test that out tomorrow. I just took new photos with my lens and see banding still. I was suppose to send my raws to canon support. I ended up forgetting the number they gave me. gonna call yous now</P><P>&nbsp;</P><P>&nbsp;</P><P>Edit: I didn't need to call, Gmail archived the number, I uploaded my raws and edits to my google drive and sent it via email. Might take a few long exposures tonight and upload those to it as well. I don't know what else to say really. Canon support guy agreed to provide free shipping back to the repair center. I told him I don't want it shipped back to me via purolator. If I do end up sending it back to Canon and its not fixed this time around <STRONG>I will be walking into the Canadian branch demanding a new DSLR body.</STRONG><BR /><BR />It seems like my camera was defective from the start. It's had a dead pixel on the LCD two days after I bought it which didn't bother me too much. I wasn't gonna make a stink with the major retailer store&nbsp;about it. I coulld've lived with it just being a dead pixel but this sensor non sense is just infuriating. I can't post process my images at all is what I'm gathering from this. with the tiniest edit the 7 lines of banding become&nbsp;really appearent. I can also see them without post processing but its really hard to see it. You'd have to be looking for it to be able to notice it.&nbsp;I might as well just shoot in jpeg or have just bought a cheap powershot camera instead.<BR /><BR />I'm not trying to be an arse and I understand stuff&nbsp;happens but it's really hard to have a calm attitude to something like this that I paid alot of money for. &nbsp;It should've been working straight from the box when I bought it or at least working properly when I recived it from repair today.I just don't want it resulting in "hey buddy! well your kinda out of luck, we've looked into your camera several times and we don't see any issues with it sorry". and me being stuck with something that's defective.maybe I'm overreacting and they've just over looked it. my&nbsp;<SPAN>suspicions tho where true</SPAN>&nbsp;when it only took them 3-4 days to "repair" it. I'd imagine it would've taken a lot longer to replace whatevers doing it and to do proper testing.<BR /><BR />Like peter said he can see the lines with minor post processing in my raws and he hasn't seen it easily in anyone elses raws except mine. I'm not trying to edit them heavly either. Heck using lightrooms dehaze tool and bringing it up to 30%~40% alone shows the bands clearly. even in Camera Raw shifting the exposure down two stops and upping the contrast just a tad without doing anything else to it, it still shows them.<BR /><BR />I don't mind waiting as long as its tested and fixed before I get it.<BR /><BR />If a mod wants to PM me to look into this to make sure my camera gets the proper inspection I would really apprecate it. I rather send my details in a private message than having my personal info out for everyone&nbsp;to see.<BR /><BR /></P>Thu, 23 Feb 2017 05:03:20 GMThttps://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/201414#M16034ElectricMuppet2017-02-23T05:03:20ZRe: Rebel T6I Sky Banding?https://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/201415#M16035

<P>&nbsp;</P><P>Great! So apperantly I'm crazy that theres no banding in my raws and its the editing software im using.... EVEN THOUGH I CAN SEE IT IN THE ORIGINAL RAWS MYSELF UNTOUCHED. Holy hell. Yup lightroom, photoshop even DPP4 no good. All bad software straight from Canon support. The only software I've been using.

<P>Canon ended up offering me free cleaning on my sensor. so that's okay then. They also said for me the mark on a peice of paper showcasing where the dead pixel is on my lcd. like others suggested I will be including printed pictures of said banding and a sd card with the images on it. So within a few day's I will be shipping my camera back to Canon. This will most likely be my last response to this thread seeing how if they don't fix the banding this time theres nothing else I can do with the suggestions you's have all given me. at that point I will be forced to bring this outside of the forum and bring this fight to Canons legal department.</P><P>&nbsp;</P><P>Sorry if my responses were&nbsp;ham-fisted.

The design of that type of sensor. Astrophotography is what I suppose Canon didn't mean when Canon wrote that the lines aren't visible in normal photo conditions.<BR /><BR />Have you tried flat field?Tue, 07 Mar 2017 09:46:09 GMThttps://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/202791#M16278Peter2017-03-07T09:46:09ZRe: Rebel T6I Sky Banding?https://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/271114#M25175

It is a sensor design and nothing that will be solved.Sat, 06 Apr 2019 23:50:30 GMThttps://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/271431#M25192Peter2019-04-06T23:50:30ZRe: Rebel T6I Sky Banding?https://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/271818#M25199
<P>Check that the problem does not appear in dark skies....thank you very much</P>Thu, 11 Apr 2019 15:51:19 GMThttps://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/271818#M25199willyfarm2019-04-11T15:51:19ZRe: Rebel T6I Sky Banding?https://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/271820#M25200
<P>It looks like the photo is slightly overexposed and I suspect a high ISO was used.&nbsp; Reducing both will help at least worth&nbsp;trying.</P>Thu, 11 Apr 2019 15:58:26 GMThttps://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/271820#M25200ebiggs12019-04-11T15:58:26ZRe: Rebel T6I Sky Banding?https://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/271832#M25201
<P>They are ligts of 20 seconds of exposure, iso 3200, it is true....in 1600 it does not appear...thanks</P>Thu, 11 Apr 2019 19:16:37 GMThttps://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/271832#M25201willyfarm2019-04-11T19:16:37ZRe: Rebel T6I Sky Banding?https://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/271889#M25202
<P>Sometimes long exposures&nbsp;like 20 or 30 seconds can cause problems not normally seen at faster exposures because&nbsp;of heat build up in the sensor.&nbsp; If you do several very long exposures&nbsp;in a row allow some cooling time between shots. It might help.</P>Fri, 12 Apr 2019 14:29:04 GMThttps://community.usa.canon.com/t5/EOS-Rebel/Rebel-T6I-Sky-Banding/m-p/271889#M25202ebiggs12019-04-12T14:29:04Z
